Mine froze up today. This is a two bolt unit that bolts to the booster. I scoured all the parts stores and unable to locate a replacement that would fit.
I did email ihpartsamerica if they had anything that would work.
Thanks!

I ended up going to the parts store and had them pull Master Brake cylinders off the shelf, well sorta, until I found one that fit and I liked.
This one has two chambers, instead of the one, so when I get around to splitting the brake system, I will be ahead of the curve.
Thanks for reading.
